Patented Nov. 17, 1931 UNITEosTArEs- PATENT OFFICE BOBELT H'. MUELLER,0F DCAJJJUR, ILLINOIS, ASSIGNOR TO MUELLER C0., 0F DE- CATUR, ILLINOIS,A CORPORATION 0F ILLINOIS SPRAY NOZZLE Application filed October 24,1929. Serial. No. 402.23'5. I

The invention relates to a spray nozzle, and more partlcularly to thatclass of spray nozzles used. as shower heads.

The object of the invention is to providea shower'head,'whereby the typeof spray can be changed,y as desired, that is, either a very fine thinspray, or a heavy coarse spray.

Another object of the invention is to provide a shower head, in whichthe spray can be practically cut ofi without the use of the usualvalves.

Still another object of the invention is to rovide af shower head whichwill-be -free rom scale, or foreign matter which generally lodges in thespray holes, causing great inefciency. l Y

With these and other objects and advantages in view, attention isVcalled to the drawin s, in which: igure 1 is a vertical cross-section ofthe shower head assembly, and

Figure 2 is a plan view of the bottom of the shower head showing thespray holes therein.

Referring more particularly to the drawings, the Ainvention provides theusual ball and socket joint, comprising the nutl internally screwthreaded at 2 for a pipe connec tion, and externally screw threaded at 3to receive the socket member 4. A spring 5 fis placed within the socketmember, and rests upon the packing such as a washer 6 which in turn fitsupon the ball member 7 which has an vorifice at its top, as at 8.Suitable packing such as a washer 9 .is placed between the bottom of thesocket member and said ball member. Extending downwardly from the ballmember through the bottom of the4 socket member, is a tubular member l0having attached thereto, at its lowermost portion in any suitablemanner, a disc 11;`

Screw threads 12 are provided near the upper portion of the tubularmemberlO, and at a point substantially midway .the -said tubular member,is a collar 13 integrally or otherwise attached thereto, which .isprovid-- ed with screw threads 14.

An enclosing member 15 substantially bell l shaped 'fits' around thetubular member 10 and is provided with internal screw threads tocorrespond with those on' said tubular member. Packing is provided at 16 between the enclosing member; 15 and the tubular member 10. A bottom17 is attached in any siutable manner' to the enclosing' member 15, andhas on its inner surface projections -IS-through which are apertures 19.It will .be noted that the aperturesare considerably largerthan thoseordinarily used and that there are no apertures directly below 'theoutlet of tubular member 10. The .disc 11 attached to the tubular member10 complete- Ily covers the apertures in the bottom of thel enclosingmember, sutlicient clearance being left between said disc and the wallsof the enclosing member to allow the latter to be moved against or .awayfrom the disc: 10.

Handles 20 may be provided on the enclosing member to facilitateoperation thereof.

The operation of the device' is`eXtremel-y (simple. and eilicient.Relative movement of the bell shaped enclosing spray member and the disc11 regulates the flow of the water and y' the desired type of spray.When the shower lodges on the projections about the openings, l it issimply necessary to tightly screw Jthe bell shaped enclosing spraymember againsttlie disc 11 and, in so doing, grlnd the scale or foreignmatter into small particles, whereby as soon as the shower head isopened, the

water will carry thescale and-foreign matter out through the enlargedholes.

It will be understood that the' embodiment of the inventiondisclosedherein is illustrative and not restrictive, and that variouschanges in the form, construction and `arspirit and scope of thefollowing claims.

I claim: 1. Ina spray ber 'a disc-like ortionsecured to the lower enthereof, an van enclosing spray member nozzle, a tubular outlet memjrangement of parts may be made within the f'.

other to regulate the spray,

associatedwith said tubular member, said members being adjustablerelativeto each 2. In a spray nozzle, a tubular ber, a disc-like portionsecured to the lower end thereof, and a substantially.bell-shapedenclosing spray member associated with said tubular outlet member, saidmembers being adjustable relative to each other to regulate the spray.

3. In a spray nozzle, a tubular outlet member, a disc-like ortionsecured to the lower end thereof, an an enclosing spray memberadjustably secured on said tubular member.

4. In a spray nozzle, a tubular outlet member,a disc-like portionsecured to the lower end thereof, an enclosing spray member associatelwith said tubular member," and means to regulate the flow of watertherethrough.

5. In a spray nozzle, a tubular outletmember, a disc-like portionsecured to the lower end thereof, a substantially bell-shaped memberadjustably secured on said tubular outlet member, and a perforated discattached atthe bottom -of said bell-shaped member.

'6. In a spray nozzle, a tubular outlet member, a disclilre portionsecured to the lower end thereof, an enclosing member adjustably securedon said tubular outlet member, and means to divert the iow of water fromsaid tubular member.

7. In a spray nozzle, a tubular outlet member, an enclosing spray memberadjustably secured on said tubular outlet member, and means to diffusethe Water through the bottom portion of said enclosing spray member.

8,. In' a spray nozzle, a tubular outlet member,.a disc-like portionsecured to the lower end thereof, and an enclosing spray memberadjustably secured on said tubular outlet member, the bottom of saidenclosing spray member having apertures therein.

9. ln a spray nozzle, a tubular outlet member, a disc-like portionsecured to the lower end thereof, and an enclosing spray memberadjustably secured on said tubular outlet member, the bottom of saidenclosing spray member having apertures therein at points Without thecircumference of said tubular outlet member.

10. In a spray nozzle, a tubular outlet member, a disc-like portionsecured to the lower end thereof, andan enclosing spray memberadjustably-secured on said tubular outlet member, the bottom of saidenclosing spray member having projections onfits inner surface, saidprojections having'A apertures therein.

11. 1n a spray nozzle, -a tubular outlet member, a disc-like portionsecured to the lower end thereof, and an enclosing spray memberadjustably secured on said'tubular outlet member, the bottom of saidenclosing spray member having circular projections on outlet'mem-A itsinner surface, said circular projections havin apertures therein.

l2. n a spray nozzle, a tubular outlet member having a disc-like portionat its lower end and an enclosing spray member adjustably secured onsaid tubular outletmember,

the bottom of said enclosing spray member having circular projections onits inner surface to form seats for said disc-like portion, saidcircular projections having apertures therein.

13. In a spray nozzle, a tubular outlet member having a disc-likeportion at its lower end and an enclosing spray member adjustablysecured on said tubular outlet member, the bottom of said enclosingspray member having4 circular projections on its inner surface at pointswithout the circumference ofsaid tubular outlet member to form seats forsaid disc-like portion, said circular projections having aperturestherein.

14. lin a spray nozzle, a tubular outiet member, an imperforatedisc-like portion secured to the lower end thereof, and an enclosingspray member, the interior diameter of which is larger than saiddisc-like portion, the tubular outlet member and the spray member beingadjustable relative to each other to regulate the spray.

15. ln a spray nozzle, a tubular outlet member, an imperforate disc-likeportion secured to the lower end thereof, and an en closing spraymember, the interior diameter of which is larger than said disc-likeportion, and provided with apertured projec tions on its inner surface,the tubular outlet member andthe spray member being adjustable relativeto each other to regulate the spray.

In testimony whereof I have hereunto set my hand.
